Liquidity Premium, Liquidity-Adjusted Return and Volatility, and Extreme Liquidity

27 Jun 2023  ·  Qi Deng, Zhong-guo Zhou ·

We establish innovative liquidity premium measures, and construct liquidity-adjusted return and volatility to model assets with extreme liquidity, represented by a portfolio of selected crypto assets, and upon which we develop a set of liquidity-adjusted ARMA-GARCH/EGARCH models. We demonstrate that these models produce superior predictability at extreme liquidity to their traditional counterparts. We provide empirical support by comparing the performances of a series of Mean Variance portfolios.
